DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0035] See also Figure 1 - Fig.12 , the present invention provides a mattress spring detection device, including a measuring frame 1, a limit assembly 2 and a pressure applying assembly 5;

[0036] Wherein, the measuring frame 1 is used to support the pressure applying assembly 5;

[0037] The limit assembly 2 includes an operating table 21, an operating compartment 22 is provided inside the operating table 21, and a plurality of sliding holes 23 are provided on the upper surface of the operating table 21. Specifically, the plurality of sliding holes 23 can be evenly distributed in an array on the upper surface of the operating table 21, such as being equidistantly arranged in three columns and three rows; a telescopic column 24 is slidably inserted in each of the sliding holes 23, and the upper end of the telescopic column 24 extends out of the upper surface of the operating table 21 to be inserted into a spring to be detected;

[0038] Furthermore, the pressure applying assembly 5 is used to simultaneously apply the same pressure to the springs to be tested.

[0039] During operation, in the prior art, when inspecting multiple springs, it is necessary to manually inspect the springs one by one, which is a cumbersome process and has a low quality inspection efficiency. However, when using the embodiment of the present invention, the springs to be inspected are firstly arranged in sequence according to the arrangement of the telescopic columns 24, and the springs to be inspected are supported by the table top of the operating table 21, and then the same pressure is applied to the multiple springs through the pressure applying component 5. Under the action of the pressure, the springs are gradually compressed, and the compression state of the springs is observed to judge the quality of the springs. In this way, by setting the pressure applying component 5 and the multiple telescopic columns 24, the effect of simultaneously inspecting multiple springs is achieved, and the inspection efficiency is improved.

[0040] Further, such as Figure 1 - Figure 2 As shown, the limit assembly 2 includes a displacement rack 25 fixedly connected to the outer wall of the telescopic column 24. In a specific implementation, the telescopic column 24 can be a hexagonal column; the displacement rack 25 is meshed with an auxiliary wheel 26 on the outside, and the auxiliary wheel 26 is rotatably connected to a limiting column 27 inside through a torsion spring. The limiting column 27 is fixedly connected to the inner wall of the operating table 21, and a detection result marking assembly 4 is arranged below the auxiliary wheel 26. The detection result marking assembly 4 includes a nozzle 461. The detection result marking assembly 4 can spray different colors of pigments through the nozzle 461 according to the number of rotations of the auxiliary wheel 26;

[0041] During operation, when the spring is tested, the pressure applying component 5 applies pressure to the spring, thereby forcing the spring to contract. During this process, the telescopic column 24 will also synchronously slide downward along the sliding hole 23. During the sliding process of the telescopic column 24, it will simultaneously drive the displacement rack 25 to move. The movement of the displacement rack 25 will drive the auxiliary wheel 26 to rotate. The quality of the spring can be judged by the number of rotations of the auxiliary wheel 26. Specifically, when the pressure applied by the pressure applying component 5 is certain, the contraction distance of a spring of qualified quality is certain, and the number of rotations of the auxiliary wheel 26 is also certain. A spring with quality defects will cause the number of rotations of the auxiliary wheel 26 to deviate. The movement of the auxiliary wheel 26 is fed back through the detection result marking component 4 to distinguish springs of unqualified quality. At the same time, through the design of the torsion spring, the telescopic column 24 is supported to prevent the telescopic column 24 from retracting into the interior of the operating table 21.

[0042] Further, such as Figure 2 - Figure 7 , Figure 13-Figure 14As shown, a display hole 28 is provided at the bottom of the telescopic column 24, a limited position slide groove 29 is provided inside the telescopic column 24 and outside the display hole 28, a marking frame 30 is slidably connected inside the telescopic column 24, a plurality of card plates 31 are fixedly connected inside the marking frame 30, a plurality of card plates 31 are provided inside each of which has through holes, a plurality of pull-out grooves 32 are provided on one side of the telescopic column 24, a plurality of pull-out grooves 32 all penetrate the marking frame 30, a marking paper 311 is slidably connected inside each of the pull-out grooves 32, an upper surface of the card plate 31 is fitted with the marking paper 311, a diameter of the through hole is smaller than a diameter of the marking paper 311, a pull-out piece 33 is fixedly connected outside the pull-out groove 32, the pull-out piece 33 is slidably connected to the pull-out groove 32, the marking paper 311 is fixedly connected to the pull-out piece 33, a clamping assembly 6 is provided outside the pull-out piece 33 at the contact position with the telescopic column 24, the clamping assembly 6 is used to clamp and pop out the pull-out piece 33;

[0043] The clamping assembly 6 includes a pair of elastic members 61, one end of each of the elastic members 61 is fixedly connected to the telescopic column 24, and the other end of each of the elastic members 61 is fixedly connected to the pull-out member 33. Magnetic blocks 62 are installed on both sides of the outer wall of the pull-out member 33, and locking columns 63 are slidably connected to the inner walls of the two magnetic blocks 62. A mounting hole matched with the locking column 63 is opened inside the telescopic column 24, and an electromagnetic locking member 64 matched with the magnetic block 62 is fixedly connected to the outside of the mounting hole. A magnetic adsorption block 65 is fixedly installed on the other end of the locking column 63, and the electromagnetic locking member 64 is matched with the magnetism of the magnetic block 62.

[0044] During operation, when the assisting wheel 26 is controlled to rotate by the displacement rack 25, the marking component 4 will spray out different colored pigments through the nozzle 461 according to the number of rotations of the assisting wheel 26, forming different marking results. These marking results will be injected into the marking paper 311 inside the pull-out slot 32 through the through hole inside the card plate 31, so that the marking paper 311 produces color. The colors of the marking papers 311 with different detection results are also different. In this way, the detection results of the spring can be automatically distinguished by the marking paper 311. After the detection is completed, the external control system will control the bottommost withdrawal piece 33 to pop it out through the clamping component 6, and finally adsorb it on the spring through the magnetic adsorption block 65, so that when the spring detection results are distinguished later, it can be done It is clear that the design of the through hole diameter being smaller than the diameter of the marking paper 311 makes it easier for the card board 31 to support the marking paper 311, thereby improving the stability of the equipment operation. At the same time, it should be noted that when installing the pull-out piece 33, the marking paper 311 is first fixedly connected to the pull-out piece 33, which can be done by pasting. After the marking paper 311 is fixedly connected to the pull-out piece 33, the pull-out piece 33 is inserted into the pull-out groove 32. At this time, the marking paper 311 will first enter the inside of the marking frame 30 along the pull-out groove 32 and be supported by the card board 31. At this time, the marking paper 311 is horizontally laid on the surface of the card board 31, and then the pull-out piece 33 enters the inside of the marking frame 30 along the pull-out groove 32. It should be noted that the width of the pull-out groove 32 should be greater than that of the marking paper 31. 1 in diameter, so as to facilitate the installation of the marking paper 311; at this time 63 will also be inserted into the installation hole at the same time, and as the installation proceeds, the elastic member 61 is compressed by the magnetic block 62 until the withdrawal member 33 is installed in place. It should be noted that the power supply of the electromagnetic locking member 64 has been turned on before installation. When the withdrawal member 33 is installed in place, the electromagnetic locking member 64 and the magnetic block 62 are adsorbed by magnetic force, thereby limiting the withdrawal member 33. At the same time, the electromagnetic locking member 64 can also play an auxiliary effect when installing the withdrawal member 33; it should be noted that the setting position of the magnetic block 62 and the magnetic adsorption block 65 needs to maintain a certain distance to avoid magnetic interference; and when the detection result marking component is running, the external control system will send an electromagnetic locking member to the electromagnetic locking member. The power control end of the component 64 sends a signal, so that the electromagnetic locking component 64 at the bottom of the telescopic column 24 is powered off and loses its magnetism, so that the elastic component 61 will reset and complete the ejection of the withdrawal component 33; the external control system will send a signal after the detection is completed, that is, the best time is when the spring is reset, so as to avoid the premature ejection of the withdrawal component 33, which will affect the reset of the spring, or the withdrawal component 33 will fall during the spring reset process; it should be noted that after the spring detection mark is completed, the withdrawal component 33 needs to be manually recovered, and multiple pull-out grooves 32 are opened inside the telescopic column 24 so that multiple marking papers 311 can be placed, and then with the use of the clamping component 6, multiple springs can be marked to achieve the effect of continuous work;After long-term use, the inside of the marking frame 30 will inevitably be stained with a lot of paint. At this time, the marking frame 30 can be replaced by a stain-free marking frame 30 through the design of sliding connection inside the telescopic column 24 to avoid affecting the detection results. The replaced marking frame 30 only needs to be cleaned and can be used again. The design of the limiting slide 29 is to play a guiding effect when installing the marking frame 30, so as to avoid the deviation of the installation direction of the marking frame 30, which will cause the marking paper 311 to be unable to be effectively installed. ;

[0045] Further, such as Fig.10 - Fig.12 As shown, the detection result marking component 4 includes a marking box 41, and a plurality of marking boxes 41 are installed inside the warehouse body of the operation warehouse 22. The upper surface of the marking box 41 is provided with a storage groove 42, and the upper surface of the marking box 41 is also symmetrically provided with displacement grooves 43. The displacement grooves 43 are located on both sides of the storage groove 42. The inner wall of the displacement groove 43 is slidably connected with a slider 44. The upper surface of the slider 44 is fixedly connected with a marking cover 45. The upper surface of the marking cover 45 is toothed. The marking cover 45 meshes with the assisting wheel 26. The storage groove 42 is installed inside the warehouse body. A paint injector 46, wherein the nozzle 461 is mounted on the upper surface of the paint injector 46, a retractable button 47 is fixedly mounted on the inner wall of the storage tank 42 on the side close to the assisting wheel 26, a paint trigger 48 is fixedly mounted on the bottom of the marking cover 45, a side of the retractable button 47 away from the paint trigger 48 is slidably connected to a limiting column 49, the limiting column 49 is fixedly connected to the marking box 41, a plurality of color control components 491 are mounted on the outer wall of the limiting column 49, and a groove for the color control component 491 to slide is provided inside the retractable button 47;

[0046] During operation, it should be noted that a slot adapted to the color control member is provided inside the telescopic button 47, so that the color control member 491 can slide inside the telescopic button 47, and a signal receiver adapted to the color control member 491 is also provided inside the telescopic button 47, and the signal receiver and the color control member 491 are connected to the control system of the color injector 46 through signals;

[0047] It should be noted that the pressure applied by the pressure applying assembly 5 to the spring should be just enough to support the displacement rack 25 to drive the assisting wheel 26 to rotate one circle, and when the assisting wheel 26 rotates one circle, the marking cover 45 just drives the pigment trigger 48 to contact the telescopic button 47;

[0048] There are three situations in the implementation process of the above embodiment, that is, when the assisting wheel 26 rotates, it drives the marking cover 45 on the marking box 41 to move along the displacement groove 43. During the movement of the marking cover 45, it also drives the pigment trigger 48 to move. At this time, there are three situations:

[0049] The first is that when the spring does not reach the predetermined retracted height under the action of the pressure applying assembly 5, the assist wheel 26 cannot rotate one circle, so the paint trigger 48 cannot contact the retractable button 47, so that the paint injector 46 cannot operate, and no paint is sprayed;

[0050] The second type is: when the spring reaches the predetermined retracted height under the action of the pressure applying assembly 5, the assisting wheel 26 rotates one circle, so the paint trigger 48 contacts the retractable button 47, and after waiting for a period of time, the paint injector 46 operates and injects a kind of paint through the nozzle 461;

[0051] The third type is: when the spring exceeds the predetermined contraction height under the action of the pressure applying component 5, the assisting wheel 26 rotates more than one circle at this time, so the pigment trigger 48 will press the telescopic button 47 at the same time after contacting it to make it contract along the color control part 491. When the spring contracts to the limit, one of the color control parts 491 will contact the signal receiver inside the telescopic button 47. After waiting for a period of time, the external pump body will input the matching pigment to the internal pump, and then complete the marking by spraying. It should be noted that in the initial state, there is a signal receiver inside that contacts it, and a period of time is required before each spraying. One is to improve the accuracy of the detection and prevent the spring from falling again during the spraying process to cause inaccurate detection results. The second is to reserve time for the sliding of the telescopic button 47.

[0052] By setting the telescopic button 47 and the color control part 491, when the spring exceeds the predetermined contraction height under the action of the pressure applying component 5, different categories of marks can be applied to it according to its actual contraction situation, thereby achieving a multi-level detection effect. When the detection is completed, the telescopic column 24 is reset to drive the displacement rack 25 to move, and then drive the marking cover 45 to reset.

[0053] Further, such as Figure 1 - Fig. 9 As shown, the force applying assembly 5 includes a top frame 51 fixedly mounted on the top of the measuring frame 1, a telescopic assembly 52 is fixedly mounted on the outer wall of the top frame 51, a mounting plate 53 is fixedly connected to the bottom end of the telescopic assembly 52, a plurality of fixed frames 54 are slidably connected inside the mounting plate 53, a plurality of power assemblies 541 are arranged on the top of the fixed frame 54, and a marking plate 56 is fixedly connected to the bottom end of the fixed frame 54;

[0054] The power assembly 541 is used to push the fixing frame 54 to move up and down. The power assembly 541 is fixedly connected to the mounting plate 53, and the marking plate 56 is fixedly connected to the telescopic column 24. It should be noted that the central axis of the marking plate 56 is in the same straight line as the central axis of the telescopic column 24.

[0055] A plurality of limit plates 57 are fixedly connected to the outside of the marking plate 56. The limit plates 57 are used to limit the spring so that the axis of the spring is in the same straight line as the axis of the telescopic column 24. The limit plates 57 are composed of a limit plate top 571, a limit plate inflection point 572 and a limit plate bottom 573. The connection between the limit plate top 571, the limit plate bottom 573 and the limit plate inflection point 572 is an arc transition.

[0056] A plurality of limit grooves 58 are provided on the upper surface of the operating table 21. The width of the limit grooves 58 matches the width of the limit plate 57. The limit grooves 58 matching the size of the limit plate 57 are provided to provide a moving track for the limit plate 57 to descend, so as not to affect the elasticity test of the spring and cause data errors.

[0057] When working, it should be noted that the telescopic component 52 can be in the form of a lead screw, a slider 44 and a motor. The motor drives the lead screw to rotate, thereby driving the reciprocating motion in the sliding hole 23 of the telescopic column 24. When in use, the spring is placed on the top surface of the sliding hole 23, and it should be noted that the spring must not cover the sliding hole 23. Then the telescopic component 52 is started to drive the mounting plate 53 to descend. During the descent, the limit plate 57 will guide the spring so that the axis of the spring is in the same straight line as the axis of the telescopic column 24. In this way, the spring can be automatically limited, thereby improving the accuracy of the detection. When the telescopic component 52 drives the marking plate 56 to descend to contact the top surface of the spring, the marking plate 56 will be automatically limited. When touched, the telescopic component 52 stops descending, and the pressure applying component 5 pushes the power component 541 to operate, and the power component 541 drives the marking plate 56 to move, thereby applying pressure to the spring, and then detecting the spring. It should be noted that the pressure applying component 5 can be a hydraulic cylinder. It should be noted that the magnitude of the pressure applied by multiple pressure applying components 5 is consistent. At the same time, it should be noted that the telescopic column 24 corresponds to the displacement rack 25 one by one, and after the detection is completed, the telescopic component 52 drives the marking plate 56 to move upward and reset, the sliding hole 23 and the telescopic column 24 are completely disengaged, and at this time the distance between the telescopic column 24 and the top surface of the operating chamber 22 is greater than the height of the spring to be detected.

[0058] Further, such as Figure 1 As shown, a support seat 70 is fixedly connected to the bottom of the measuring frame 1, moving wheels 71 are arranged at the bottom of the two support seats 70, and a base 72 is arranged between the outer walls of the two support seats 70;

[0059] During operation, the top frame 51 is used to install the control element, the control element is used to control the marking plate 56 to move downward, the support seat 70 and the base 72 are used to support the entire device, and the moving wheel 71 is used to control the movement of the entire device.

[0060] Through the design of the embodiment of the present invention, the effects of automatic detection of multiple springs and automatic marking of detection results are achieved. In this way, the steps of feeding the springs, loading the materials, and screening the springs according to the detection results can be carried out by mechanized equipment without manual participation, laying the foundation for improving the automation rate of mattress spring detection.
